wrong, a hollow point does not explode it expands on impact
Bullets do not explode (minus some military loads) when they hit something, they might fragment, deform, etc..
A conventional explosion is detonated on contact or impact. The conventional explosion has a fission ignite. This means it explodes upon impact and needs a primary explosive to ignite.
This will depend upon what it hits, what type of bullet it is, the angle of impact, the angle of reflection, if any rotation or torsion is placed upon the bullet, the depth of the impacted object, etc. The deceleration can vary from 100% (the bullet stops) to less than 1% (practically no energy lost) depending upon the interaction of the above variables.
I presume you mean for a bullet? The casing allows the bullet to grip the internal rifling of the barrel without shearing the soft lead of the bullet. The tip helps the bullet expand upon impact allowing all the energy of the moving bullet to be passed on to the thing you have pointed the gun at.
He allowed us to take pictures of extremely high speed events, such as the path of a fired bullet, or the exact instant that a balloon explodes, or the wave pattern that a water drop makes.
When the striker on the gun strikes the primer, it explodes, causing the gunpowder in the casing to ingite. The explosion propels the bullet down the barrel.
it means the zombie explodes and when it explodes it just depends but mostly they explode upon death
All firearms need: A projectile such as a bullet, gun powder to propel the bullet out of the barrel of the gun, and a cartridge to hold them together. Gun powder only explodes and the force from the explosion propels the bullet out of the barrel, basically. The cartridge is disposed of thereafter. A bullet will not move unless the gunpowder behind it explodes. This is the basic operation of a firearm/rifle.
It depends on what you mean by "average impact."
It explodes
Because when it is hit with the heat it explodes and the explosion/hot air pushes the bullet forward!
